Getting Started

A template for kick starting a Cloudflare worker that protects some URL by verifying a JWT generated by the Lit Protocol using Javascript

How this works

This CF worker will check for a jwt query parameter and verify that it was signed by the Lit Protocol. If the JWT is valid, the worker will return a 302 redirect to a protected URL. If the JWT is invalid, the worker will return a 401 response.

Usage

You will need Cloudflare Wrangler to build and deploy this. Install it using the instructions here: https://developers.cloudflare.com/workers/cli-wrangler/install-update

After installing it, run "wrangler login" to log in to your cloudflare account.

Next, open index.js. Every line that has a comment that starts with "LIT Developers" is something you should look at.

Specifically, you should set the protectedUrl variable on line 22 to the final URL you want to send your users to, if they authenticate successfully.

Building and Deploying on cloudflare

With wrangler, you can build, test, and deploy your Worker with the following commands:

# builds your project with webpack
wrangler build

# run your Worker in an ideal development workflow (with a local server, file watcher & more)
wrangler dev

# deploy your Worker globally to the Cloudflare network (update your wrangler.toml file for configuration)
wrangler publish
